Some funds have minimum time limits that apply after you've moved your monies from that fund, before you can repurchase said fund. I think 60 or 90 days is probably the average, however, not all funds require this moratorium, and certainly none of the money market funds do. With these time freezes in place, the number of moves really doesn't matter. I think new monies can always be invested in any fund, as has been suggested in previous posts.
